TriangleAngleGeometric Construction
In collections Transformations and triangle congruence
This example illustrates that Angle-Side-Angle (ASA) is a criterion for triangle congruence. It involves core math concepts like triangle congruence, angle measurement, and distance calculation. Constructed using GeoGebra commands such as Polygon, Intersect, Segment, Angle, Distance, and Point. Suitable for middle school and above students learning geometric proofs.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C) → poly1, c, a, b
  2. Intersect(xAxis, yAxis) → D_1
  3. Segment(E, D) → d
  4. Segment(E, H) → e
  5. Segment(D, H) → f
  6. Angle(B, A, C) → α
  7. Angle(C, B, A) → β
  8. Angle(A, C, B) → γ
  9. Distance(b, c) → g
  10. Distance(d, a) → h
  11. Angle(H, E, D) → δ
  12. Angle(E, D, H) → ε
  13. Point(e) → E_1
  14. Point(f) → G
